I am always excited when a mini-ITX motherboard bound for the mainstream market crosses my desk. In a small PCB, compared to full sized ATX, it can be difficult to have a feature filled product that stands up to scrutiny. Today we have the Z87I under the hammer, MSI’s small solution to Z87 Haswell.

MSI Z87I Overview

After recently reviewing MSI’s Z87 heavyweight, the MSI Z87 XPower, moving to something smaller means I want to see how much of that big product can be retained down the stack. The MSI Z87I comes in at $140, and there are some noticeable differences (apart from the size) compared to the bigger brothers.

Nonetheless, the MSI Z87 is geared up for Ethernet network connectivity, with two Realtek NICs. We do have WiFi onboard, although this is the 802.11n 2.4 GHz Centrino N-2230 solution we saw on the XPower – not the 5 GHz dual band option I would prefer in all WiFi enabled motherboards. This amount of extra network controllers is due to the Flex IO allocation – as the board only has four SATA 6 Gbps and six USB 3.0 from the chipset, this gives the other 8 Flex IO lanes all the PCIe 2.0 for these controllers. Video outputs come via a HDMI, DisplayPort and combination DVI-I, and the board also sports the Realtek ALC892 audio codec.

Being a mini-ITX motherboard, our auto overclock options are limited. On almost all mainstream MSI Z87 motherboards we get an OC Genie button giving a one press overclock – this functionality is relegated to BIOS and software with the Z87I, giving only one option to 4.0 GHz. The BIOS is better than the Z77 brethren, offering a better visual representation of fan speeds (which still need a better upgrade, but is a step in the right direction) and a hardware monitor to detect when hardware is not recognized in the motherboard. There is still room to improve the BIOS, especially in how the overclocking options are organized, although word from MSI is that this will be changed in due course. With the motherboard I reached a 4.6 GHz overclock manually, although the BIOS limited the CPU voltage to 1.3 volts.

Software is a little different, with Command Center offering voltages up to 2.1 volts (not a good idea) but features like the RAMDisk are a bonus. Live Update 5 works well at updating the system software and drivers, although in our testing it had trouble updating itself, causing me to recommend users get the latest version from the website.

In terms of results, the Z87I performance is a little strange - despite having MultiCore Turbo enabled by default it does perform worse than expected on a number of computational benchmarks. The one flaw that stood out of the testing was my 2D explicit grid solver test, where the MSI strangely scores 15% less than the rest of our Z87 testing. Discrete GPU and USB testing are on par with other Z87 motherboards without boosting features, and POST times under Windows 7 with a discrete GPU were great, scoring under 9.2 seconds.

The MSI Z87I offers a nice motherboard for users needing multi-LAN functionality, and Live Update 5 will keep it up to date. The decision to go with the N-2230 is one that baffles me to no end, and I hope that MSI offer a dual band SKU by default, or even an 802.11ac SKU.

Visual Inspection

As with almost all mini-ITX motherboards the main concern comes at the socket placement, and here MSI have placed the socket up against the DRAM slots but almost 1cm away from the PCIe slot. This might be a nudge towards the MSI Lightning range of GPUs which have a bulkier rear plate than most. The small VRM heatsink is to the left of the socket and did not get in the way of any of my coolers, though the close proximity to the DRAM slots made my TRUE Copper heatsink clash with the Corsair Vengeance Pro memory.

The socket area has access to two fan headers – one four-pin CPU header above the socket between the chipset and WiFi module, and a four-pin SYS fan to the left of the chipset. Ideally on a motherboard this size I would prefer three fan headers where possible, although it is not necessarily a deal breaker.

The CPU 4-pin power connector is in a slightly better place than what we saw in the last mini-ITX motherboard review – here we get it just above the power delivery heatsink. My main argument on the 4-pin power connector is that wherever it is, a cable has to reach it, and I would prefer if this cable did not have to go across all of the motherboard components. With this location on the Z87I, it seems best to come at it from the direction of the SATA ports if from above is not possible.

Moving clockwise around the motherboard and we get a USB 2.0 header above the front panel header. This is an odd location for a front panel header, also confusing due to the lack of on-board lettering telling users which pins are which. The SATA 6 Gbps ports are at the top of the motherboard next to the USB 3.0 header, both preferred places for these ports. Between the chipset and the WiFi module we also have a COM header. The DRAM slots use single sided latches, which are my preferred option when large GPUs may be in use.

The decision to use Centrino N-2230 is a big glaring amber light on this motherboard, as any preferred dual band solution, even for an extra $5, would be preferred. Due to the size of the motherboard I was not expecting any additional controllers, but I am glad to see a DVI-I port rather than a standard DVI-D and disregard the VGA entirely.

The big selling point for this motherboard will be the multi-network functionality, though in order to get group discounts from Realtek MSI has used standard ALC892 audio solution which performed average in our audio tests. If MSI were aiming more at a HTPC or gaming market, we might have seen an ALC898, as I suspect the ALC892 saves a few cents off the overall cost.

the tech media is amazingly quiet about the usb3 lga1150 bug... and the coming fix.

they are also quiet about i7-4770r lack of availability, along with any iris pro solution actually being buyable... is everyone waiting for c2 chipsets to launch significant products with haswell?Reply

The reason for that is because the Haswell USB3.0 bug is not that relevant in desktops. It affects notebooks more and only affects USB3.0 storage devices when waking up from an S3 state, in which the data becomes unreadable off of the device.

So unless you never turn your computer off, always have some sort of USB3.0 device connected and set aggressive power saving, you will be completely unaffected by the bug.

i7-4770R is BGA and needs to be packaged together with a mobo, so it's only natural that it has a slower development cycle. It's also likely that it's going to get a similar treatment to NUC or BRIX, so that's going to be an even longer delay.Reply

not relevant on desktops? any computer that goes to s3 is effected...most people don't turn "off" their computer anymore... they let it idle and sleep.lots of people use USB storage devices, when they plug in their phone its a usb storage device, their camera, their backup external HDD, etc.. some people use USB drives as their primary storage for music/movies..

you don't have to "always have" a usb device connected... just once... and you may see the bug.

I think more people should be aware of it, and yet no one is talking about it.... not enough.

It's on the worst thing in the world, but either is waiting a month or two for the fix.

I imagine apple is buying all the iris pro cpus up and will ship computers with them when c2 is ready...Reply

I stopped reading when I saw the mini pci-e slot taken up by a wireless card. It doesn't look like you could fit a mSATA card without interfering with the CPU Heatsink. Again, another model packing all sorts of features that I will not use. Reply
